ther outwardly, the standard terminations 9 are bent at a right angle downwardly and have fastened thereon a vertical open ended cylindrical member 12 concentric with and extending above the member 1 and also above the lower portion of the upper cone 11.

As before stated, the vertically adjustable and rotatable sleeve member 13 is manually operable from below to vary the area of the discharging interspace of the member 1 and the inverted frustal top part 15 of the smokepipe receiving sleeve 16. This feature renders the appliance convenient for use on buildings of different character or dimensions, in the regulation of the ventilating discharge current of air rising from below when heated, the vitiated air escaping from within the outer member 12, but the conical top ele- ..ment 11 being of greater diameter than the said discharge vent, prevents down drafts enw tering either said regulated interspace or the smoke-pipe members 15 and 16 and the smoke-pipe.

A horizontal current of air crossing the upper part of the device and the open upper end of the circumferential member 12-, will induce a suction in the latter, also in the ventilator member 13 and the smoke-pipe terminal 15 and 16, which will aid in their discharge, respectively of the vitiated air in the building and the gaseous products of combustion of a heater therein. Rising currents of air without will, when entering the member 12 from below, be largely prevented from entering the smoke-pipe or the ventilator discharge opening, by reason of the superposed flarlng arts of the element 15, the cone 11 above, an also the flaring marginal parts of the sleeve 13 A special use and convenience is afforded in that the inverted frustal margin 15 of the.

smoke-pipe sleeve 16 projects outwardly far enough beyond the ventilator member 1 so that sparks from the smoke-pipe cannot fall back into the member 1 and into the building below.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. A device of the character described, comprising in combination, a hollow openended ventilator member in communication with a building, a wider superposed upwardly flared deflector with depending sleeve spaced from said member concentrically, and rotatable means including a flared element whose flared part is parallel with the flared part of said deflector, for vertical adjustments of said sleeve either varying or closing the interspace between them.

2. A device of the character described, comprising in combination, a hollow open- .ended ventilator member in communication with a building, a wider superposed upwardly flared deflector with depending sleeve supported and spaced relative to said member concentrically, outwardly flared and downwardly sleeved means for adjustably either varying or closing the interspace of said member and deflector, and a downwardly 'concaved cap wider than and-supported in inverted frustum wider'than the' ventilator member and spaced therefrom, a downwardly concaved cap supported above and spaced from said flared member concentrically and wider than it and said ventilator member, a hollow cylinder ro-tatably fitting within the upper part of said ventilator member and having a flaring top parallel with the flared margin of said sleeve and alined therewith, adjusting means for'said cylinder to variably space it from the flaring margin of said frustum, and a hollow'open-ended inclosure member concentrically spaced from and around the interspaces of said ventilator member, and said cap.

4. A device of the character described, comprising in combination, a hollow openended ventilator member in communication with a building, a smoke-pipe sleeve having a'part depending centrally into said member and having an outwardly flared upper margin above and wider than the upper end of said member, standards fixed on the-outer wall of said ventilator member upon which the flared part of said sleeve is fixed, the in termediate portions of the standards being provided with horizontally alined cross corrugations, a hollow rotatable member de pending within said ventilator member from the top and having a top outwardly flared margin seated within alined corrugations of said standards, said margin having circum ferentially spaced recesses to release it from said standards to allow longitudinal adjustments thereof when rotated and then elevat-" ed or lowered relatively thereto.

In testimony whereof I affix my signature.
